I received my GigaBox as part of upgrade from connect 300. After setting up the GigaBox, the WiFi keeps disconnecting every 10 seconds. Even ran the network diagnostics on the router page and that also keeps showing issue with WiFi a number of times.
I see you've separated your WIFIs in terms of name. Do you have the interruptions on the 5GHz or 2.4GHz? Did you upgrade your modem? How far away from the modem are your devices? Do you use a WIFI booster?
